The net-next-hw spinners on netdev.bots.linux.dev observe failing so-txtime-py tests. A review of stdout shows most failures to be due to exceeding the 4ms grace period. All I saw were within 8ms. So increase to that. Double the bounds from 4 to 8ms. This is still is small enough to differentiate the delays programmed by the test, 10 and 20ms.
